Clinical value of color dopper ultrasound in detection of carotid atherosclerosis

【Objective】To evaluate the color doppler flow imaging(CDFI)in detection of carotid atherosclerosis and clinical value.【Methods】To observe the common carotid artery and its bifurcation,the internal carotid artery,external carotid artery intima-media thickness,plaque echo and hemodynamic changes.【Results】3670 cases of this group,1874 cases without carotid artery disease(51.1%),and atherosclerosis were 1796 cases(48.9%).In suffering from arteriosclerosis, only in the performance of membrane thickening or plaques are accompanied by 692 cases(38.5%),the mild carotid artery stenosis in 381 cases(21.2%),moderate stenosis in 423 cases(23.6%),severe stenosis in 266 cases(14.8%),carotid artery occlusion were 34 cases(1.9%).In this group,by CT,MRI diagnosed 612 cases of cerebral infarction patients,including 456 cases of carotid artery ultrasound to detect atherosclerosis,accounting for 74.51%.In 685 cases with diabetes and hypertension,CDFI detected 577 cases of carotid atherosclerosis,accounting for 84%.【Conclusions】CDFI,which provides carotid intima-media thickening and plaque and other medical information,has a higher atherosclerosis detection rate in patients with hypertension and diabetes than normal.CDFI can be preferred used in detection of carotid atherosclerosis which has important clinical value.
